vUIT @To JOSEPH T. MERCIER, OF CHICAGO, ILLINOIS.

VENTILATOR.

To all whom 'it may concern Be it known that I, JOSEPH T. Mentana, a citizen of the United States, residing at Chicago, in the county oit Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

rThe present invention relates to a ventilator particularly designed and adapted for use upon traveling conveyances.

The objects of the present invention are to provide a ventilator which is of a cheap, simple and durable construction, and to so arrange the parts thereof that they will act as a preventive to the entrance of cinders and other debris through the openings in the ventilator and into the interior oit the conveyance.

A further object of the invention is to provide means for accumulating a mass of air below the ventilator, which can be readily sucked or drawn through the ventilator into the compartment.

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a vertical section of the ventilator of the present in vention, showing it secured in operative position; Fig. 2, a cross-section of the ventilater of the present invention; and Fig. 8, ay plan view of the ventilator in operative position.

The present invention relates to a ventilator in the form of a register or grid, which is especially adapted to be placed in the itloor of a car body adjacent a heating surtace, for the purpose of admitting air 'trom below the heater into the interior of the car.

The ventilator of the present invention is not of a formation to draw air into the car body unless suction is applied through some other means to draw the air therethrough. That is, before air in any appreciable amount will pass through the ventilator` the ventilating means at the upper end of the car must be put in operation. It is the intention to draw rather than force the air through the ventilator.

The invention in the form illustrated comprises a framework 4, which consists of vertically depending walls 5, terminating in horizontally extending flanges 6, adapted to be secured by any suitable means to a portion of a car body 7 As heretofore stated, the invention is par- Specicaton of Letters Patent.

ticularly adapted for use in the flooring of the car, although, obviously, il the requirements jl'lstify, it may be placed in other portions of the car, where it could perform its 'function in substantially the saine way. The walls 5 in the form shown are joined together by cross piecesl S ot' suitable construction and formation; and extending between the "alls 5 is a series of upper slatlike ineinbers 9 and lower slat-like members l0. liv referring to Fig. 2, it will be seen that each of these Slat-like members is spaced apart from one anothers providing a series oil up per openings or slots 11, and lower openings or slots It will further be seen, from a study of Fig. that the slats t) and 10 are so arranged with respect to one another as to place thc slots 11 and 12 out of alineiueut with one another. This arrangcnientI is provided to impede or help to prevent the entrance of cinders or other debris through the radiator or grid into the interior of the car, The upper Slat-like members 9 are preferably of a concave-convex formation in cross section, as shown in Fig. '2. This is also for the purpose ol assisting in the pre. vention of the entrance of cinders and other debris into the interior of the car through the register or grid, it being obvious that if "l said cinders should enter through the openings 12, they would strike the concave surface of the sections 9 and be deflected down and away from the openings '11.

Lying below the members 10 and extending between the plates 5 is a plate 13, the platos 5 and 13 being arranged with respect to one another in the construction shown to form an I. The plate 18 serves two functions: First, the cinders and other debris striking against this plate will be stopped and deflected, and thus prevented from entering:r the openings 1Q; and, second, the plate 13. in conjunction with the plates 5, forms a three sided receptacle, which provides a compartment below the register or grid surface, in which air will pack or accumulate, so that it can be readily drawn through the radiator or grid and into the interior of the car. It. is obvious that when this device is placed upon a moving body, and the plate 13 is facing in the direction of travel of said body. the air striking the plate 13 will be cheeked and a certain portion of it will 'accumulate between the plates 13 and 5, the plates 5 serving to prevent the air from spreading sidewise and away from the grid surface.

That is, what may be said to be an accumulated pocket of air will always be present between the plates 13 and 5; and this pocket will provide a constant supply of air, which will be sucked through the grid or register and into the interior of the car. lt will be noted that the plate 13 is lying approximately midway of the plates 5. This is so that it will act with equal efficiency whichever direction the conveyance is moving.

t is an obvious fact that with a swiftly moving conveyance there will be a constant rush of air below the conveyance. If some means are not provided for checking and accumulating this air, it will rush by the ventilating grid or opening and only a small portion of it will be extracted and drawn into the car, since the force of suction tending to draw it inward would have to be stronger than the force tending to draw it past the ventilator.

As will be understood Jfrom the foregoing description, there are three means provided in the ventilator oi'l the present invention tor preventing the entrance of cinders or other debris through the grid and into the interior of the car: First, said debris will strike the plate 13 and be arrested in its momentum, so that gravity will carry it downward and away from the grid openings; second, said grid openings are placed out orp alinement with one another, so that there is no direct entrance from the outside to the inside oi the car; and, third, the upper sections of the grid or opening are of a curved formation, which tends to deflect said debris away 'from the upper of the openings.

I claim:

1. In a ventilator of the class described, the combination of a trame work comprising two side plates, a series of upper slats and a series of lower slats secured to said plates, said slats being arranged in odset relation to one another, a plate rigidly secured to said side plates at approximately the center thereof, said rigidly secured plate extending outwardly from said slats and from a pointimmediately below said slats to the outer end of the side plates, substantially as described.

2. In a ventilator of the class described, the combination of a trame worl comprising two side plates, a series of upper slats and a series of lower slats secured to said plates, said slats being arranged in offset relation to one another, the lower of said slats being straight faced and the upper of said slats being of convex formation in cross section, a plate rigidly secured to said side plates at approximately the center thereof, said plate extending outwardly from said slats and from a point immediately below said slats to the lower edge of the side plates, substantially as described.
